T 0 all whom it may concern.

Be it known that we, ERNEST D. AmmasoN, a citizen of the United States,.and resident of New York city, borough of Man hattan, county and State of New York, and CARL BECKMANN, a subject of Germany, and residentof New York city, county of Queens, New York, have invented certain new and useful Improvements in Packaging Machines, of which the following is a specification.

Our invention relates to improvements in machines for charging receptacles or cartons with goods and has for its principal object to remove a receptacle or carton in the event that the same is not charged or is. only partly charged with the required amount of goods, to prevent such charged or partly charged receptacle or carton from being carried along with the fully charged receptacles or cartons.

In the form of machine illustrated in the accompanying drawings we provide means to support the receptacles or cartons in position to be charged with goods, means to charge the required goods in the receptacles and means to extract or remove a receptacle from its support in the event that such receptacle is not charged with the required quantity of goods or number of articles. In the form of machine shown inthe accompanying drawings we provide means to successively charge a receptacle or carton with two articles and means operating automatically to extract or withdraw the receptacle from its supporting means in the event that such receptacle should not be charged or should only be charged with one such article. It will be understood, however, that the mechanism hereinafter set forth may be adapted to charge the receptacles or cartons with any desired quantity ofgoods or number of articles and to extract receptacles or cartons in case any lesser quantity of goods or number of articles is charged in the receptacles or cartons or no charges be inserted.

Our invention comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereol, wheremachine embodying our invention; F ig. 2

is a cross section substantially on the plane of the line 2-2 in Fig. 1; Fig. 8 is a cross section on the line 3 3 in Fig. 2; Fig. 4 is a cross section on the line &4 in Fig. 2; Fig. 5 is a cross section on the line 55 in Fig l; Figs. 6, 7 and 8 are detail cross sections on plane of line 8-8 in Fig. 1; Figs. 9 and 10 are enlarged detail cross sections on line 99 in Fig. l; and Fig. 11 is an enlarged detail plan view of parts shown in Fig. 9.

Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates the main frame of the machine which may be of any suitable construction. At 2 is indicated a support in the form of a conveyor for receptacles or cartons 3 tobe charged, which conveyer may be in the form of an endless chain provided with receivers 2' spaced thereon to receive and propel thereceptaclcs 3. The conveyer 2 may be supported at opposite ends upon spaced sprocket wheels 1; carried by shafts 5 journaled in the main frame in any well known, manner. Said conveyor may be driven in any desired manner, step by step. We have illustrated mechanism, such as at Geneva movement,

for operating the conveyer, comprising an arm 6 on shaft 7 journaled in hearings on the main frame, which arm has a projection 8 to engage at Geneva member 9 on shaft Shaft T is shown provided with a gear 10 in mesh with a pinion 11 on shaft 12 journaled on the main frame and provided with a pulley 13 receiving belt 14 from a suitable source of power. For each rotation of arm 6 the conveyor will be operated a step. The upper run of conveyer 2 may travel upon a longitudinal guideway 15 supported on the main frame, and bars or rails 16 supported by the main frame over the conveyor serve to retain the receptacles or cartons 3 in proper position on the conveyer as the receptacles are carried along by the latter. The receptacles or cartons 3 may be successively applied in thereceivers ofthe conveyer by manual operation main frame. Said shaft may be rocked by aerank arm '22 and link 23 actuated in any suitable manner, as by means of a bell crank 24 on shaft 25 journaled on the main frame. -Link 26 connected with said crank has a projection27 to beioperated'by a cam,

her. In the accompanying drawings we have position adapted to contain the articles a.

which may be in gear 10, where y for each rotation of said gear'the shaft '21 will be rocked back and forth. A spring 18 cooperates with the opener 17 in connection with arm 19,. Devices for operating the opener may be adopted substantially similar to t-ho se' set forthiri the patent to E. D. Anderson, No. 1,151,233, dated August 24,

The article or goods a to be charged into the open receptacles 3 may be sxippliedand fed to the receptacles in any suitable manillustrated means to supply said articles and charge a plurality thereof into the open receptacles 3 as follows :--A hopper 28 (Figs 2, 3 and 4) is shown supported in an inclined Said hopper isshown journaled 'at'i ts' lower portion at 29' upon uprights 30 on the main frame solthat the hopper ma be rocked.

Said hopper shown provided with lat erally extending arm 31 connected with depending rod. or link 32 opcratively connected with a crank arm 33 carried by a shaft jourtnaled on the main frame and connected with a sprocket wheel 34' receiving a chain 35 from a drive sprocket 36 secured on shaft 5' whereby as saidshaft is rotated thehopper will berocke d. Hopper 28 is shownprd videdwith: an inclined bottom 28 to deliver articles therefromto chute 37 which inclines downwardly over guide or block 38 sup;

ported upon the main frame by support 39 (Fig. 2). The upper endof the chute 37 is shown supported upon a rod 40' carried byuprights 30. Thedownwardly inclined "bottom 28 of the hopper isshown separated at the middle portionand provided with interposed'spaced bars 41 supported by cross pieces 42- carried by the hopper. A separatingbar 43 at the bottom of the hopper between bars 4 1 divides at 4:3? to provide tWorunways-for the articles a from the hopper for dischargin" into two chutes 37 that 're'speetivelyterm nate over the corre-' sponding bloclt 38.: Iii" the example illusdownthe chutes. Rails 44 may be supported P the il *byMans of strips 45 secured to the rails and having rods or the like 46 depending and secured to lugs or projections 4*7at the side of a chute Since the chutes communicate with the delivery end of the hopper'the' articles a 'will be de livered from the hopper to the chutesas the hopper is rocked; and the articles will be shifted aronnd ihthehopper so that they be pushed therefrom towards the receptacles will-slide therefrom i'ntothe' chutes. At the 3 when the latter are brought to rest successively opposite said heads. The heads'48 have end pivots 50 journaled in jawshor supports 51 associated with guides or blocks 38. The heads 48; may be given rocking movement, timed'with' relation to the stop ping of open receptacles 3 "posite the heads,by'any' suitable means. ihads 48 are shown provided with crank arms" 52 piv otally connected with' depending rod 53, the

lower ends of which rods are guided in guides 53"carried"by'-the main frame (Figs. 1 and 2). Each rod 53 is provided with a projection 54 disposed in mam-slot 55 in a bar 55 guided toreciprocate in a "guidewa'y inor on support'39. The shape of slot 55*is such thatwhen ear 55 is in a retracted position rod 53 will havebeen moved to cause head 48 to be ro'tated tohiring its channel or passage-"49in register with the articles a inthe correspondihg chute 3T 'toreceive an article (Fig.5). An abutment or stop 56'is shown located on the side ofhead 48 adjacent to the conv'eyer-and a receptacle-thereon to temporarily retain an article a in pas-- sage 49. passage 49 willresist the advance'of other articles in the chute and when bar 55 is moved to the right in Fig. 2 rod will be moved downwardly to {cause head 48 "to rock At such time said "articlein a suitable distance to present said articled I is, shown provided with a lower horizontal portion of suflicient length to permit the desired movement of bar without then operating head 48. The several heads l8 operate approximately together to simultaneously register articles a in spaced heads 48 with spaced receptacles 3 on conveyor 2. At the time that the heads :8 have been moved to present the articles a ins-aid heads in position to enter the opposing receptacle 3 pusher or plunger 57 for each head is moved forwardly to push the article a. "from corresponding head l8 into the opposing receptacle 3, T and 8). Pusher or plunger 57 is pivotally connected with the corresponding bar 55 at 58 and is guided in away 38 in the corresponding block 38 to enter the passage 49 in the opposing head 48 (Figs. 6, 7, and 8). Bar 55 is pivotally connected by link 55' with crank-arm 58 on rock-shaft 21. As said shaft is rocked the bars 55 and pushers 57 will be reciprocated together. The length of pushers 57 with relation to slots 55 of bars is such that when said pushers and bars are moved in one direction, as to the right in F 2, the bars will first cause operation of heads 48 to align their passagesdfl with the pushers and a farther movement oi bars with the pushers will cause the latter to pass through the corresponding passages $9 to eject articles (L therefrom and push the latter into receptacles 3 (Figs. 7 and 8). On the return movement of said bars and pushers the latter will bewithdrawn from heads 18 just before'the raised cam-like parts of slots 55 cooperate with pins 5% to cause 'rods to rise and return heads 48 to the article receiving positions. (hen the heads 48 are out of article receiving position the lowermost articles a in chutes 37, by resting against the surfaces of said heads, will be retained in the chutes, but as soon as passages -19 have been brought to register with the chutes the lowermost articles will slide from the'chutes into passages 49 respectively to be stopped against abutments 56. and so on for each reciprocation of bars and pushers or plungers The devices described provide means for separating the articles a from the bulk thereof. aligning the separated or selected articles with the receptaeles 3 and charging the selected articles into the receptacles.

The receptacles may be charged with any desired quantity or number of goods or articles. In the example illustrated the charging means are adapted to feed one article a at a time into a receptacle, and with two of such charging means spaced apart each carton should be charged with two articles (I- one. after another. The arrangement shown is such that at the position A in Fig. i one article (4 will be fed into a receptacle (Fig. 7), and when such partly charged receptacle has been stepped by the conveyor to position B is Fig. 1 another article a will be fed into said receptacle. the last ted article pushing the first fed article farther into said receptacle (Fig. 8).

Our invention enables the extraction from the conveyor oi a receptacle 3 in case the latter is partly charged with the required goods or articles or in case it is not charged at all. In the term of invention illustrated we utilize the full charge or the absence o'l such full charge in a receptacle as a determining factor in the extraction or noncxtraction of such receptacle from the conveyer. To accomplish the aforesaid results we have illustrated means as follows :At a point along the conveyer designated by the letter C, Fig. 1, at a positionwhere the conveyer comes to rest with charged receptacles, we locate receptacle extracting'devices before the point of delivery of the finished receptacles "from the conveyor. A reciprocative linger or teeler 60 is carried by a bar 61 on one side of the conveyor opposing a stop or abutment 62 on the opposite side of the conveyor (Figs. 1, 9, 10 and 11). The stop 62 is shown carried by the guideway 15. The bar 61 is shown guided to reciprocate along guide bars 63, 6a supported in horizontal position by upright 65 on main frame 1. When finger 60 and bar 1 are retracted to the dotted position shown in F igs. S) and 1O the receptacles 3 may pass between said finger and the stop 62. Associated with finger 60 are grippers (36, G7, the inner ends of which oppose said finger to grip receptacles. Said grippers are shown pivot-ally supported at (38 upon projections (59 extending from bar ('31; The outer ends of grippers 66, 67 are shown connected by springs 70 with bar 61, tending to cause the inner ends of the grippers to approach linger 60. The grippers 66, 67 respectively have lateral pins or projections (36", (37 adapted to encounter abutments 71, 72 shown carried by upright 65; (Figs. 9 and lo). provided with inclined portions '71, 72*. to engage the pins cc", 6? respectively to cause tilting of the grippers (3(3. 37 when the grippers recede from the conveyor, as indicated in Figs. 9 and 10 in dotted lines. At T3. H are receptacle discharging stops, shown on opposite sides of the path oil finger (30 (Fig. ll) to encounter receptacles carried by said finger and the grippers to discharge the receptacles therefrom. Any suitable means may be provided. to reciprocate the linger (it) and thegrippers. We have shown a reciprocative bar T5 having a longitudinal slot 75 receiving a lateral pin 76 extending from bar (51 (Fig. 11). A spring 77 connected with bar 75 at 78 and with pin 76 (Fig. 9) serves to draw the bar 61 toward the left in the drawings to permit rod'Tfi The abutinents ll, 72 are shown pers will grip said flaps.

to move independently of pin 76 for a limited distance. The rod 75 is shown pivotally connected with a rock arm 79 pivotally supported on the main frame by bracket 80, said arm 7 9 being shown pivotally connected with a link 81. The link 81 is shown pivotally connected with a crank arm 82 secured on rock shaft 21. As said shaft is rocked the rod 75 will be reciprocated to reciprocate bar 61 the finger and the grippers with it. hen the open receptacles or cartons 3 are brought to rest opposite the charging devices'thelatter will operate to charge the articles a into said receptacles. The conveyer ,will also bring the charged receptac les. to rest opposite the devices to extract fromthe conveyer any uncharged orpartly charged receptacles When the conveyer stops a charged receptacle 3 between finger 6O andv the stop 62 said fingerwill advance with grippers 66, 67, while the pushers advance to charge-receptacles, and the finger will encounter an article a in the receptacle and push the same. i The stop 62 will limit the movement of article' orarticles a within the receptacle whereby further progress of finger 60 will be arrested by the article or articles a opposing the same, thereby to prevent the grippers 66, 67 from engaging receptacle 3, see Fig. 9. The bar 75. will continue to the end. of its stroke, the spring '77 then expanding, the slot of bar 75 sliding on pin 7 6. The said operations permit finger 60 to remain temporarily pressed against article a in the receptaclef Upon the return stroke of bar 75 it will encounter pin 76 and push bar 61, finger 60 and the grippers away from said receptacle and pushers 57 will recede from the receptacles Whenthe finger and pusher-s are away from ing stop 62, (-Fig. 10). The said advance of finger 60 will be SllifiClBIlt to cause the grippers 66, 67 to engage the adjacent part of the receptacle to grip it to the finger during the advance stroke of bar 7 5. When the receptacles have end laps 3 the grip- On the return stroke of bar 75 it will push bar 61 away from the receptacle and the finger 60 and the grippers that engage the receptacle will extract the receptacle 3 from the conveyer.

. Continued movement ofthe finger and grippers away-from the conveyer willcause the pins 66, 67 to encounter the abutments 71,.

with the conveyers from the extracting devices said receptacles may be removed from the machine many desired or usual way,

,When the receptacles have end flaps the lat ter may be closed in any suitable manner. We have illustrated movable flap closers 83,

84, operated by arms 85, 86 connected'by' link 87 and. actuated to rock by arm 88 op- I vices for the flaps 3'are indicated generally Our invention provides simple and effec: tive means to assure that" receptacles or cartons 3 discharged at the delivery end D of the machine will be properly charged, as required, to assure against the. delivery of uncharged or with the desi charged receptacles, thereby overcoming the disadvantage sometimes experienced with automatic packing mm chines of delivering improperly charged receppaclesor cartons with charged ones.
